My forehead pores look particularly prominent. What kind of treatment would be best?

Lately, every time I look in the mirror, I keep getting self-conscious about the pores on my forehead. I think my forehead used to be on the smoother side, but at some point, pores started appearing one by one, and now, when I look at it under the light, my skin looks bumpy and uneven overall.

I don't mind the oiliness on my nose and cheeks since they tend to be naturally sebum-prone, but now that my pores are becoming prominent on my forehead as well, I am really self-conscious about applying makeup. In particular, when I apply foundation, it looks like it gets stuck in the pores, making my skin look even messier.

I am wondering if enlarged forehead pores are caused by sebum secretion or if they are related to skin elasticity or aging. I feel that home care alone has its limits, so I am looking into dermatological treatments. What procedures are effective for improving forehead pores?

I would also like to ask if skin texture can improve along with pore treatment, and how many sessions are usually required to notice a change.
